Correction of aberrations via polarization in single layer metalenses
Augusto Martins, Kezheng Li, Guilherme S. Arruda +6
The correction of multiple aberrations in an optical system requires different optical elements, which increases its cost and complexity. Metasurfaces hold great promise to providi…
Diagnosing numerical Cherenkov instabilities in relativistic plasma simulations based on general meshes
D. -Y. Na, J. L. Nicolini, R. Lee +3
Numerical Cherenkov radiation (NCR) or instability is a detrimental effect frequently found in electromagnetic particle-in-cell (EM-PIC) simulations involving relativistic plasma b…
Perturbing beyond the shallow amplitude regime: Green's function scattering formalism with Bloch modes
A. Abass, A. Martins, S. Nanz +3
We present a Bloch modes' based Green's function scattering formalism for cost efficient forward modelling of disordered binary surface textures. The usage of Bloch modes of an unp…
Finite Element Time-Domain Body-of-Revolution Maxwell Solver based on Discrete Exterior Calculus
Dong-Yeop Na, Ben-Hur V. Borges, Fernando L. Teixeira
We present a finite-element time-domain (FETD) Maxwell solver for the analysis of body-of-revolution (BOR) geometries based on discrete exterior calculus (DEC) of differential form…
Axisymmetric Charge-Conservative Electromagnetic Particle Simulation Algorithm on Unstructured Grids: Application to Microwave Vacuum Electronic Devices
Dong-Yeop Na, Yuri A. Omelchenko, Haksu Moon +2
We present a 2.5-dimensional charge-conservative electromagnetic particle-in-cell (EM-PIC) algorithm optimized for the analysis of vacuum electronic devices (VED) with cylindrical…
